# Dependencies for generated files unfortunately need to be declared manually.
# This is because dependency scanning is a gross shitty hack by concept, and
# requires that the compiler successfully compiles a file to get its
# dependencies. This results in a chicken-and-egg problem, and in conclusion
# it works for static header files only.
# If any headers include generated headers, you need to manually set
# dependencies on all source files that include these headers!
# And because make is fucking shit, you actually need to set these on all files
# that are generated from these sources, instead of the source files. Make rules
# specify recipes, not dependencies.
# (Possible counter measures: always generate them with an order dependency, or
#  introduce separate dependency scanner step for creating .d files.)
